That is (was) correct, I wrote it.

Correction, that claim was correct.

We can go either way.  Obviously, my preference was to support this,
and I did.  I suspect the person that broke this, did it on accident,
as otherwise they would have updated the documentation and removed all
the other bits to support this (libgcc2.c):

void *
__throw_type_match (void *catch_type, void *throw_type, void *obj)
{
#if 0
 printf ("__throw_type_match (): catch_type = %s, throw_type = %s\n",
  catch_type, throw_type);
#endif
 if (strcmp ((const char *)catch_type, (const char *)throw_type) == 0)
   return obj;
 return 0;
}


Jason, what direction did you want to take this?
